| 摘 要： | 针对Ｈｏｐｆｉｅｌｄ网络的局限性，本文提出了对Ｈｏｐｆｉｅｌｄ模型及联想记忆算法的改进：（１）改变其权对称性（２）引入反传学习算法（３）为避免在学习过程中出现振荡，引入基本反传值，并作了理论上的分析，运用改进的Ｈｏｐｆｉｅｌｄ网络进行相近的汉字识别，取得了较好效果。

| Abstract: | A method is pressnted to improve Hopfield Network in this paper.(1)Making weigths of IINN unsymmetrical (2)Back Propagation Learning Algorithm is introduced (3)To avoid oscillating while learning,Basic Backprogation Value is also proposed. The algorthm is also analysed in the paper.When used to recognize Charactcr,the algorithm proves to be quite satisfactory. |
